The Numera® PERS-4200X medical alert system works together with its compatible PERS wearables and home sensors from the Numera Home Safety Hub (SSC00101). This suite of personal emergency response system products combines information from sensing devices like CO and smoke detectors, motion detectors, and activity sensors with alerts from wearable personal emergency response devices in a single Personal Emergency Response Solution (PERS) console for seniors or others needing support while living alone. Having a personal emergency alert device on you at all times ensures your safety and security should a medical emergency arise.
